The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Karramarro.
To be honest, mate, we’ve got a bit of a flat spell to start. There’s nothing worthwhile on offer for the first few days. The water’s sitting at 77°, which is much warmer than normal for this time of year – about 7° above average, so that’s something to peel a layer off for.
Tuesday the 21st and Wednesday the 22nd are a write-off: tiny, weak, cross-onshore junk. Thursday morning the 23rd goes glassy, but the swell’s only 3ft with a short period of 6 seconds – not enough to get excited about. Friday the 24th drops off even more. We’re looking at a dry run until the weekend.
The first real sign of life shows up Saturday the 25th. A WNW swell pushes in – 6ft in the morning, climbing to 8ft by the afternoon with a period of 7 seconds. The combined energy is moderate to strong (217 in the morning, ramping up to 718 by the arvo). Winds are cross-offshore and clean, so it’ll look surfable, but this is advanced territory. Anything over 8ft is for experts only, and the short period means it’ll be a bit crumbly. Still, it’s the best we’ve seen so far. Sunday the 26th holds similar size – 5ft to 6ft – but with rain showers and moderate cross-off winds. The energy drops a notch (187 to 254), but it’s still clean.
Now, Monday the 27th brings a jump in quality. The swell hits 6ft, but the period lengthens to 9–10 seconds, and the energy jumps into the 500s (538 in the morning, 573 in the afternoon). That’s a solid groundswell pulse. Winds are light and cross, turning cross-onshore later, so morning will be the better window. The 6ft size is pushing it for beginners, but it’s well within reach for intermediate and above.
The standout of the whole outlook is Tuesday the 28th. Morning glass – dead flat wind – with a 5ft NW swell at 10 seconds. The energy is strong at 380, and with glassy conditions, Karramarro will be clean and lined up. The swell direction (NW) matches the optimum NW for this point break, so it’s a proper setup. This is your best chance for a quality session. The afternoon turns cross-onshore, so get in early.
Wednesday the 29th and Thursday the 30th see the swell easing (4ft down to 3ft), but periods stay in the 9–10 second range, and the energy drops to 315 then 165. Thursday morning has light cross-off winds and clean conditions – surfable but ordinary. After that, from Friday the 31st through to the 5th of August, we’re back to small, weak, and mostly cross-onshore junk. The 1st of August has a faint 0.7ft WNW swell with a 13-second period, but it’s just not enough to work with.
So to wrap it up: the first week is a slow burner. Saturday the 25th gets things moving for the experts, but the real gem is Tuesday morning, the 28th – glassy, 5ft, groundswell, and the break doing what it does best. After that, it fades out again. Get on it while it’s there.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
